PAINT COMPOUND.

7 Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed February 6, 1905. Serial No. 244,498.

To all whom it may concern:

Be it known that I, ALEXANDER A. EnnnsoN a citizen oi the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Paint Compounds, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a new and useful improvement in paints or coloring pigments, the object being to impart to the finished product the properties and characteristics of red lead and to avoid the disadvantages connected with the use and manufacture of pure red lead. I

In the manufacture of pure red lead it is customary to take the scraps and tailings accumulating in the factory contain a core or center of metallic lead, so that when ing or cracking off of same.

My present invention is designed to correct the objec- 'tions existing in commercial red lead as sold on the market by the use of a filler or body combined in certain proportions with the rod lead, whereby the percentage 9f the metallic particles and the excessive oxidizing properties are proportionately decreased in the bulk of the finished productmade according to my invention, and further, While my product possesses the good qualitics of red lead so far as a heavy body, drying properties and permanency of color are concerned, the proportion of impurities and metallic particles in the finished product is reduced to about one-third of the quantity of such particles existing in commercial rcd lcad. My im- 1 proved product also possesses the advantage that when used for certain purposes, such as ior all general painting'purposes, it will surpass in durability, rust-proof and corrosive qualities'ordinary commercial lead oxid.

To make 1,510 poundsoi my improvedpaint, I pro cecd in the followinginanncr ln a suitable vat into which 500 pounds oi lead oxid and 1,000 pounds of colored permanent red bar ytcs of proper shade in the form of an impalpably fine powder is placed, the lead oxid and barytes is thoroughly mixed and while mixing this mass I add about twenty gallons of water in which have been dissolved opounds oi SL1l-SO(lEL: The mass is again thoroughly mixed and about 20 gallons of water into which have been dissolved 5 pounds of horns; arc now added, the sal-soda and horax thoroughly assimilating and fixing the mass of previously stained barytes and lead oxid, alter which this mass is then run through a grinding mill so that it is thoroughly mixed and ground. The resulting product is a pasty mass possessing the color of red had and this is placed in .1110 4 usual drying pans for the purpose of evaporating the water.

Having thus described the invention, what is claimed as now and desired to be secured by Letters Patent is:

point compound consisting of 500 pounds of red lead and 1,000 pounds permanent red colored hai'ytes having a lixod color corresponding to that of the red loud, thoroughly mixed with pounds sail-soda dissolved into 20 gallons oi water and 5 pounds horax dissolved in 20 gallons oi water.

in testimony whereof, I hereunto :iflix my signature, in the presence of two witnesses this fourth day or February 1005.
